The cavity chamber is fitted with a vacuum self-drainage system and balancers on each valve discs. For most physical safety, GEA makes use of the Venturi impact which is created by the special form of the move channels, inflicting a vacuum on the alternative seal during lifting, stopping strain increases. As a result, no cleansing liquid can enter the other pipe carrying the product whereas a valve seat is being lifted or cleaned, even if a seal is defective.
When new methods are arrange and adjusted in a brief while, there is a higher danger of overpressure during operation. Under wraps should stay in place when water hammer happens, and the valve should stay closed.

This makes the closed valve proof against water hammer up to 50 bar within the higher and lower pipelines. The new MX valve kind additionally has an integrated balancer cleansing device. It ensures that the balancer is totally flushed from the surface during seat lifting concurrently cleaning-in-place is taking place. All surfaces involved with the product can be cleaned without any additional components protecting the product from contamination.
